This is a working example on how to store CryptoKeys locally in your browser. We are able to save the objects, without serializing them. This means we can keep them not exportable (which might be more secure?? not sure what attack vectors this prevents).

To try out this example, first make sure you are in a browser that has support for async...await and indexedDB (latest chrome canary with chrome://flags "Enable Experimental Javascript" works). Load some page and copy and paste this code into the console. Then call encryptDataSaveKey(). This will create a private/public key pair and encrypted some random data with the private key. Then save both of them. Now reload the page, copy in the code, and run loadKeyDecryptData(). It will load the keys and encrypted data and decrypt it. You should see the same data logged both times.

Chromium OS ft. Docker

Chromium OS is cool. Chromium OS with crouton is cooler. Chromium OS with Docker is even cooler. This is specifically a guide for the Chromebook Pixel 2 (2015), but I can't think of any reason it wouldn't work with other devices.

1. Create a build environment
2. Customize the kernel
3. Build Chromium OS
4. Flash Chromium OS to USB
5. Install Chromium OS
